If it were the passenger side, I'd bet the "flapper" was frozen up and 
forcing the exhaust through the crossover..

Since it's the driver's side.. there's always a good chance something 
has crawled up inside and died in the muffler. :D  Or worse, made a nest.

Of course, that doesn't explain the clatter.. but would explain a change 
in "puff" at the tailpipe.  Heck, an exhaust leak could..

In any case, I think to "fix" the problem, he'll need to do a little 
disassembly.. I'd probably pull the pan first and look for bearings 
before bothering to pull the valve covers and try to de-gunk the 
drainbacks.. if there's bearing in the pan, don't waste your time with 
the drainback. :)

How much for this AA unit to put the 402 in?  AA is always proud of 
their stuff (perhaps rightly so).. rebuilding an SV might be the more 
economical approach, and it's definitely a lot less headache.

Could get lucky and only need a bearing and cleaning.. that's never MY 
luck, of course..
